Description
Die Erfindung betrifft ein Parkhilfesystem für Kraftfahrzeuge, mit Sensoren zur Erfassung eines Parkraums in der Umgebung eines Kraftfahrzeugs, mit einer Auswerteeinheit, mit der die mit Hilfe der Sensoren gewonnenen Informationen zur Ermittlung einer Trajektorie des Kraftfahrzeugs für einen Einpark- oder Ausparkvorgang verarbeitbar sind, wobei eine Ausgabeeinheit vorgesehen ist, die dem Fahrer des Kraftfahrzeugs auf Grundlage der ermittelten Trajektorie Fahrhinweise anzeigt oder mitteilt.The The invention relates to a parking assistance system for motor vehicles, with sensors for detecting a parking space in the vicinity of a motor vehicle, with an evaluation unit, with which the obtained with the help of the sensors Information for determining a trajectory of the motor vehicle for one Parking or Ausparkvorgang are processable, wherein an output unit is provided on the basis of the driver of the motor vehicle the determined trajectory indicates or notifies driving instructions.
Mit diesen Parkhilfesystemen kann beispielsweise die Länge und Tiefe einer Parklücke und die Position beziehungsweise die Orientierung des Kraftfahrzeuges relativ zu der Parklücke ermittelt werden. Diese Informationen, die während des Einparkvorgangs aktualisiert werden können, dienen dazu, den Fahrer des Kraftfahrzeugs eine Hilfestellung zu geben, welche Vorgänge er ausführen muss, um das Kraftfahrzeug in einen Parkraum hinein- oder aus diesem herauszubewegen. Die Fahrhinweise, die dem Fahrer während eines Einpark- oder Ausparkvorgangs gegeben werden, können dem Fahrer beispielsweise auf einem Bildschirm angezeigt und/oder über Lautsprecher akustisch mitgeteilt werden. Die Fahrhinweise können Hinweise der Art "Fahrzeug anhalten", "Lenkrad maximal nach links einschlagen" oder dergleichen umfassen.With These parking assistance systems can, for example, the length and Depth of a parking space and the position or orientation of the motor vehicle relative to the parking space be determined. This information is updated during the parking process can be serve to assist the driver of the motor vehicle give what operations he perform must enter or leave the motor vehicle in or out of a parking space out move. The driving instructions given to the driver during a Parking or Ausparkvorgangs be given, for example, the driver displayed on a screen and / or acoustically via speakers be communicated. The driving hints can show hints of the kind "vehicle stop", "steering wheel maximum after turn left "or the like.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Genauigkeit und die Bedienungsfreundlichkeit des eingangs genannten Parkhilfesystems zu verbessern.Of the The present invention is based on the object of accuracy and the ease of use of the aforementioned parking aid system to improve.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Parkhilfesystem Bremsmittel umfasst, die für ein Abbremsen des Kraftfahrzeugs an oder benachbart zu Fahrtrichtungsumkehrpunkten und/oder Fahrtrichtungsänderungspunkten der ermittelten Trajektorie ansteuerbar sind. Hiermit ist es möglich, dass das Einhalten der Fahrtrichtungsumkehrpunkte und/oder Fahrtrichtungsänderungspunkte unabhängig von der Geschicklichkeit des Fahrers des Kraftfahrzeugs gewährleistet ist. Durch das Abbremsen des Kraftfahrzeugs an den Fahrtrichtungsumkehrpunkten können diese exakt eingehalten werden. Durch das Abbremsen an den Fahrtrichtungsänderungspunkten kann der Fahrer exakt an den Wendepunkten einer Einpark- oder Ausparktrajektorie entsprechende Fahrhinweise zur Bewegung des Lenkrads umsetzen. An den Fahrtrichtungsänderungspunkten ist es nicht erforderlich, dass das Kraftfahrzeug vollständig abgebremst wird. Dies kann jedoch vorteilhaft sein, insbesondere bei Kraftfahrzeugen, bei denen eine hohe Lenkkraftunterstützung bei niedrigen Geschwindigkeiten vorgesehen ist. Auf diese Weise können auch sehr knapp bemessene Parkräume genutzt werden, da mit dem erfindungsgemäßen Parkhilfesystem die Einhaltung der optimalen Trajektorie möglich ist.These Task is inventively characterized solved, that the parking aid system comprises braking means for braking of the motor vehicle at or adjacent to turning direction reversal points and / or direction change points the determined trajectory are controllable. Hereby it is possible that adherence to the direction reversal points and / or direction change points independently is ensured by the skill of the driver of the motor vehicle. By braking the motor vehicle at the reversal points can these are adhered to exactly. By braking at the direction change points the driver can exactly at the turning points of a parking or Ausparktrajektorie implement appropriate driving instructions to move the steering wheel. At the direction change points it is not necessary that the vehicle is completely decelerated becomes. However, this can be advantageous, especially in motor vehicles, where a high power steering at low speeds is provided. This way can also be very tight Park Facilities be used, as with the parking aid system according to the invention compliance the optimal trajectory possible is.
Die Bremsmittel können unabhängig von dem Bremssystem des Kraftfahrzeugs bereitgestellt werden. Vorteilhaft ist es jedoch, wenn die Bremsmittel Teil des Bremssystems des Kraftfahrzeugs sind. Somit können die Komponenten des vorhandenen Bremssystems des Kraftfahrzeugs genutzt werden.The Braking agents can independently be provided by the brake system of the motor vehicle. Advantageous However, it is when the brake means part of the braking system of the motor vehicle are. Thus, you can the components of the existing brake system of the motor vehicle be used.
Vorteilhafterweise ist vorgesehen, dass die Bremsmittel von der Auswerteeinheit angesteuert sind. Hierdurch ist das Parkhilfesystem unabhängig von weiteren Steuergeräten. Selbstverständlich kann die Auswerteeinheit des Parkhilfesystems auch mit Steuergeräten eines Bremssystems eines Kraftfahrzeugs kommunizieren.advantageously, is provided that the braking means are controlled by the evaluation unit. As a result, the parking assistance system is independent of other control devices. Of course, the Evaluation unit of the parking aid system also with control units of a Braking system of a motor vehicle communicate.
Weiterhin ist es vorteilhaft, wenn das Parkhilfesystem Kraftunterbrechungsmittel zur Unterbrechung des Kraftflusses zwischen einer Brennkraftmaschine und den Antriebsrädern des Kraftfahrzeugs umfasst. Hierdurch ist es möglich, die Bewegung des Kraftfahrzeugs nicht nur über den Eingriff der Bremsmittel zu beeinflussen, sondern zusätzlich durch die Ansteuerung der Kraftunterbrechungsmittel. So kann beispielsweise einem Bremsvorgang vorgeschaltet ein Kraftunterbrechungsmittel so angesteuert werden, dass der Kraftfluss zwischen der Brennkraftmaschine und den Antriebsrädern des Kraftfahrzeugs unterbrochen ist, so dass ein besonders weiches Abbremsen des Kraftfahrzeugs bei Annäherung an einen Fahrtrichtungsumkehrpunkt oder -änderungspunkt ermöglicht ist.Farther it is advantageous if the parking aid system power interruption means for interrupting the power flow between an internal combustion engine and the drive wheels of the motor vehicle. This makes it possible to control the movement of the motor vehicle not just about to influence the engagement of the braking means, but in addition by the activation of the power interruption means. So, for example preceded by a braking force interruption means so be controlled that the power flow between the internal combustion engine and the drive wheels of the motor vehicle is interrupted, so that a particularly soft Braking the motor vehicle when approaching a reversal point or change point allows is.
Die Kraftunterbrechungsmittel können beispielsweise durch eine Kupplung eines Schaltgetriebes des Kraftfahrzeugs oder durch den Freilauf eines Automatikgetriebes des Kraftfahrzeugs gebildet sein.The Force interruption means can for example, by a clutch of a gearbox of the motor vehicle or by the freewheel of an automatic transmission of the motor vehicle be formed.
Besonders vorteilhaft ist es dabei, wenn die Kraftunterbrechungsmittel von der Auswerteeinheit angesteuert sind, um zu erreichen, dass das Parkhilfesystem weitestgehend unabhängig von weiteren Steuergeräten des Kraftfahrzeugs arbeiten kann.Especially it is advantageous if the power interruption means of the evaluation unit are driven in order to achieve that Parking assistance system largely independent of other control devices of the Motor vehicle can work.
Nach einer Weiterbildung der Erfindung ist für eine Bewegung des Kraftfahrzeugs entlang der Trajektorie eine Maximalgeschwindigkeit vorgebbar. Bei Überschreitung dieser Maximalgeschwindigkeit kann mit Hilfe der Bremsmittel des Parkhilfesystem das Kraftfahrzeug abgebremst werden, so dass ein reibungsloser Parkvorgang gewährleistet ist.To a development of the invention is for a movement of the motor vehicle along the trajectory a maximum speed can be specified. When exceeded This maximum speed can be achieved with the help of the braking means of the Parking assistance system, the motor vehicle to be braked, so that a smoother Parking guaranteed is.
Die Erfindung betrifft ferner ein Verfahren zum Betrieb eines Parkhilfesystems mit den vorstehend beschriebenen Merkmalen. Bei diesem Verfahren werden die Bremsmittel und/oder die Kraftunterbrechungsmittel so angesteuert, dass die Geschwindigkeit des Kraftfahrzeugs an den Fahrtrichtungsumkehrpunkten und/oder Fahrtrichtungsänderungspunkten gegenüber einer Ausgangsgeschwindigkeit verringert ist. Die Geschwindigkeit kann dabei auch an den Fahrtrichtungsänderungspunkten bis auf 0 abgesenkt werden.The invention further relates to a method for operating a parking aid system having the features described above. In this method, the braking means and / or the force interrupting means are controlled so that the speed of the motor vehicle to the direction of travel traffic points and / or direction change points is reduced compared to an initial speed. The speed can also be lowered to 0 at the direction change points.
Besonders vorteilhaft ist es, wenn den Fahrtrichtungsumkehrpunkten und/oder Fahrtrichtungsänderungspunkten ein Bremsbereich vorgeschaltet ist, in dem eine gleichmäßige Verringerung der Geschwindigkeit des Kraftfahrzeugs stattfindet. Dies bewirkt, dass ein Kraftfahrzeug, das sich einem Fahrtrichtungsumkehrpunkt oder einem Fahrtrichtungsänderungspunkt nähert, weich und daher für den Fahrer des Kraftfahrzeugs angenehm abgebremst werden kann.Especially It is advantageous if the reversing points and / or Vehicular turning points a braking area is connected upstream in which a uniform reduction the speed of the motor vehicle takes place. This causes, that a motor vehicle, which is a turnaround point or a turnaround point approaches, soft and therefore for the driver of the motor vehicle can be braked pleasantly.
